Nonfree actions of countable groups and their characters
A. M. Vershik St. Petersburg Department of V. A. Steklov Institute of Mathematics, Russian Academy of Sciences, St. Petersburg, Russia
Abstract:
We introduce a number of definitions of nonfree actions of groups. The most important of them is that of a totally nonfree action; it is naturally related to the theory of characters of groups and their factor representations. This short note is a brief exposition of a part of a more detailed paper on this subject, which is now in preparation. Bibl. 8 titles.
Key words and phrases:
nonfree actions, lattice of subgroups, characters, factor representations.
